    Abstract: A method of BLE-Mesh communications includes providing a dual-mode BLE-Mesh device including dual-mode RF driver, dual-mode manager, a BLE stack for BLE operations, and a mesh stack for mesh operations in a BLE-mesh network having a BLE relay device and a functional end BLE device. The BLE-mesh device has a periodic set of time indexed data slots common throughout the BLE-mesh network which provides a BLE event timeline for BLE connection events. The dual-mode BLE device implements an event clustering algorithm that delays or advances mesh events with respect to a timing the BLE connection events for clustering together their respective occurrences into continuous BLE/Mesh events to reduce a duty cycle by reducing a number of transitions from active mode to sleep mode and from sleep mode to active mode. The BLE-Mesh device communicates in the BLE-mesh network using the continuous BLE/Mesh events with at least one mesh device.

    Abstract: A method for concurrent execution of multiple protocols using a single radio of a wireless communication device is provided that includes receiving, in a radio command scheduler, a first radio command from a first protocol stack of a plurality of protocol states executing on the wireless communication device, determining a scheduling policy for the first radio command based on a current state of each protocol stack of the plurality of protocol stacks, and scheduling the first radio command in a radio command queue for the radio based on the scheduling policy, wherein the radio command scheduler uses the radio command queue to schedule radio commands received from the plurality of protocol stacks.

    Abstract: Excessive latencies and power consumption are avoided when a large number of leaf nodes (LNs) contend simultaneously to join a time slotted channel hopping wireless communication network having a root node (RN) interfaced to LNs by one or more intermediate nodes (INs). A first plurality of shared transmit/receive slots (STRSs) is allocated for at least one IN, and a second plurality of STRSs is advertised for use by contending LNs, where the first plurality is larger than the second plurality. When a LN joins, its STRSs are re-defined such that most become shared transmit-only slots (STOSs) and no STRSs remain. The numbers of STRSs allocated to INs may vary inversely with their hop counts from the RN. One or more STOSs may be added for each of one or more INs in response to a predetermined network condition.
